Figure 5. The interplay between the fiber wall morphology, residual charge, and three charge effects (global, local, and polarization). (A–C) Dependence of
characteristic surface on β. α = 3; β = 0.1, 1.5 and 3 for (A), (B), and (C), respectively; ξ = 10, η = 1and K = 2. The dash-dotted lines denote the prescribed
toolpath, and the red curves denote the actual deposition trajectory. Since there is currently no way to determine β, the characteristic surfaces and the
actual deposition trajectories may not exactly match as shown, therefore, (A–C) are qualitatively showing the dependence of jet deposition trajectory on
β. (D–F) show the dependence of lateral characteristic curves at different z on β. Α = 3, ξ = 10, η = 1 and K = 1. (A), (B), and (C) correspond to the blue,
green, and red curves in (D), (E) and (F), respectively. The purple rectangle in (F) denotes the region dominated by the polarization effect. (G) shows the
evolution of wall structure with layer number. (H) schematizes the process of the jet approaching the intersection point after the lateral deviation has been
formed. Point P on the incoming jet will be deposited on point R on the preexisting fiber. (I) summarizes the interplay of fiber morphologies, residual
charge, and three charge effects (global, local, and polarization). Moreover, the ways in which different parameters factor into this interplay are also shown.
